What are your thoughts on people saying high fat diets cause insulin resistance?

This is a keto sub so obviously most of us will be on the same page here and share similar opinions for the most part, but what are your thoughts/ responses to people that say high fat diets cause insulin resistance? With all of the different types of information out there, there are many different opinions from people that don’t correlate with each other. I’ve seen quite a few people saying things like “ high carb diets don’t cause insulin resistance but high fat diets do”. So what’s your take on this? Is there a bit of truth? Is it blasphemy? I’m curious to see yall responses to this
